33 | ;; | |
34 | ;; The speedbar provides a frame in which files, and locations in | |
58bd8bf9 CY |
35 | ;; files are displayed. These items can be clicked on with mouse-2 in |
36 | ;; to display that file location. | |

58bd8bf9 CY |
44 | ;; Users of really old emacsen without the need timer functions |
45 | ;; will not have speedbar updating automatically. Use "g" to refresh | |
46 | ;; the display after changing directories. Remember, do not interrupt | |
47 | ;; the stealthy updates or your display may not be completely | |
48 | ;; refreshed. | |
